I've noticed a weird issue with Synchronize view. I have about two
sets of projects (about 20 projects each) checked out locally. The only
difference is that one set is for trunk and another is from some branch.
I have to do that because Subclipse don't allow to switch multiple
projects to another branch in one action (see bugs 472 and 596) it is
easier/faster to delete projects from Eclipse and import different set
when you need to jump between trunk and branch.

I also have a working set for those projects and created
synchronization for the whole working set in the Synchronize view. It
all work nice, except that synchronization goes completely crazy after I
delete and import projects from different location in svn. So, I have to
delete synchronization and create it again after every reimporting.
